Video and portrait inputs
Choose MP4, MOV, WebM, or M4V video up to 120 seconds, or use a portrait photo when the Talking Photo capability is active.
Visemix
Visemix is a browser-based AI lip sync generator that synchronizes mouth movement in a video or supported portrait-photo workflow to uploaded audio, a recording, or text. It is intended for creators, educators, marketers, and localization workflows that need private, reviewable talking-video outputs.
AI lip sync generation with local file checks
Visemix is a browser-based AI lip sync video generator for matching a person’s visible mouth movement to a separate voice track. Users can start with a video or, when enabled, a portrait photo for a Talking Photo result, then add uploaded audio, a browser recording, or text-to-speech input.
The workflow is designed around a local file check before upload. After the source and voice pass checks, users sign in, review the credit estimate and permissions, and request private generation. Results can be inspected in Activity and downloaded without a Visemix watermark; the service advises reviewing difficult frames rather than treating successful completion as a quality guarantee.
Core features
Flexible voice sources
Supply a separate MP3, WAV, M4A, or WebM track, record voice in the browser, or enter text for text-to-speech when available.
Local preflight checks
The browser checks format, size, duration, resolution, readable tracks, and timing before upload or credit use, helping identify input problems early.
Selectable quality levels
Select Standard, Pro, or Ultra quality before generation. Standard uses one credit per audio second, while Pro and Ultra use four and seven times the Standard rate respectively.
Private generation and review
After an explicit signed-in submission, the job is generated privately and the result can be reviewed in Activity and downloaded without a Visemix watermark.
Credit and job controls
Monthly and annual plans provide 2–4 concurrent generations depending on the plan, while one-time credit packs provide one concurrent generation; confirmed failed jobs return reserved credits.
Practical use cases
Creator videos
Apply a new authorized voice track to existing talking-head footage while keeping the original person, setting, and framing as stable as the source allows.
Social content
Build short vertical clips from portrait or landscape source footage and review mouth timing before publishing to a social channel.
Localization previews
Prepare a localized version of approved footage by pairing it with translated speech; the site describes this as a planned workflow rather than a released end-to-end dubbing tool.
Marketing and product explainers
Create presenter-style explainers or campaign drafts from authorized footage and a prepared narration track, with frame-by-frame review for difficult sections.
Education and training
Produce lessons or training material with synchronized narration, using clear, front-facing source footage and reviewing the output for intelligibility and facial stability.
Pros and Cons
Pros

- Offers several voice-input methods: uploaded audio, browser recording, and text-to-speech when available.
- Checks media locally before upload for format, size, duration, resolution, tracks, and timing issues.
- Private storage, signed download URLs, watermark-free downloads, and automatic credit returns for confirmed failed jobs are documented.
Cons
- Final quality depends on source conditions such as face visibility, camera angle, motion, occlusion, cuts, and audio timing; local checks cannot guarantee the final result.
- The listed plan limits cap video jobs at 120 seconds and Talking Photo jobs at 60 seconds, and credits are consumed according to audio duration and selected quality.
- Public sharing, batch processing, HD, and API capabilities are not included in the current plans.
FAQ
What source files and durations does Visemix support?
Visemix accepts MP4, MOV, WebM, and M4V video files up to 120 seconds. The page also supports portrait-photo input when the Talking Photo capability is active; the displayed limit for Talking Photo is up to 60 seconds per job on the listed plans.
How can I provide the voice track?
You can upload an audio file in MP3, WAV, M4A, or WebM format, up to 120 seconds, or use text-to-speech when that capability is available. Browser recording is also offered as a voice-input method.
Are files uploaded during the local file check?
The browser checks format, file size, duration, resolution, readable tracks, and audio timing before upload. These checks happen locally and do not spend credits; files upload only after you sign in and explicitly request generation.
Are generated videos private and watermark-free?
Completed videos generated with trial, one-time, or subscription credits can be downloaded without a Visemix watermark. Generated media is stored privately, and downloads use short-lived signed URLs; public sharing is not included in the current plans.
What happens if a generation fails?
A confirmed failed generation returns the credits reserved for that job. Before retrying, review the displayed error and improve the source, especially when the face is in profile, the mouth is hidden, or the source contains difficult motion or cuts.
